ABSTRACT

A new and distinct  Magnolia  cultivar named ‘Melissa Parris’ is disclosed, characterized by having pleasantly scented pink flowers, a dominant central leader, and large tardily deciduous foliage. The new variety is a  Magnolia , normally produced as a medium to large ornamental tree.

Latin name: Magnolia hybrida.

Varietal denomination: ‘Melissa Parris’.

STATEMENT REGARDING FEDERAL SPONSORSHIP

No federal funding was involved in the research or development associated with this invention.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of a deciduous Magnolia hybrid resulting from the intentional breeding of Magnolia [tripetala x (tripetala x obovata)] ‘Silk Road’ with Magnolia insignis MGA 355, now registered as the cultivar Magnolia insignis ‘Anita Figlar’. The objective of the breeding effort was to produce a large pink flowered magnolia cultivar that would flower after typical spring frosts. Pollen from harvested flowers of unpatented selection Magnolia insignis ‘Anita Figlar’, in Six Mile, S.C., was isolated and dehisced by co-inventor Parris in May 2010, and subsequently used to hand pollinate flowers of the unpatented selection Magnolia hybrid ‘Silk Road’ by co-inventor Ledvina in Green Bay, Wis. A portion of the resulting seeds from the cross were carefully collected, and thereafter germinated and planted in Spartanburd, S.C. by co-inventor Parris in 2011. The resulting new variety was grown to flowering age in full sun, and first observed to flower in May 2014. The plant was thereafter selected for propagation by co-inventor Parris in May 2015 after observing prolific, ornamental flowering that commenced after the last average frost date in the upstate of South Carolina. The present exemplar stands 20 feet (6.0 m) tall by 8 feet (2.4 m) diameter. It has demonstrated excellent hardiness, having withstood Summer temperatures of 101° F. (38° C.) and Winter low temperatures of 6° F. (−14° C.).

Asexual reproduction of the cultivar ‘Melissa Parris’ has been repeatedly conducted under the direction of co-inventor Parris from vegetative cuttings in Gainesville, Ga. and Spartanburg, S.C. Small rooted cuttings from the novel plant have flowered and grown with vigor, thereby demonstrating that the cultivar is stable. Co-inventor Parris has also successfully reproduced the cultivar by chip budding using in-ground and container specimens of the hybrid Magnolia yuyuanensis x Magnolia insignis as rootstock.

SUMMARY OF THE INVENTION

The cultivar ‘Melissa Parris’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in temperature, day length, moisture availability, and light intensity, however no variance in genotype would result, as may be determined by genetic characterization, with methods such as inter-simple sequence repeat (ISSR) markers.

The following traits have been repeatedly observed and are determined to be the unique characteristics of Magnolia ‘Melissa Parris’. These characteristics in combination distinguish ‘Melissa Parris’ as a new and distinct cultivar.

-   -   1. ‘Melissa Parris’ exhibits hybrid vigor     -   2. ‘Melissa Parris’ exhibits a dominant central leader with         compact branch arrangement     -   3. ‘Melissa Parris’ exhibits large attractive glossy foliage     -   4. ‘Melissa Parris’ exhibits relatively large, lotus-like         flowers     -   5. ‘Melissa Parris’ exhibits pink outer tepals having a color of         RHS Red-Purple Group 65A     -   6. ‘Melissa Parris’ exhibits alternate pink and white striated         inner tepals     -   7. ‘Melissa Parris’ produces a pleasant sweet citrus-like floral         fragrance     -   8. ‘Melissa Parris’ exhibits late Spring to early Summer bloom

PARENT COMPARISON

Plants of the new cultivar ‘Melissa Parris’ exhibit intermediate characteristics between that of the seed parent, Magnolia hybrid ‘Silk Road’, and that of the pollen parent Magnolia insignis ‘Anita Figlar’.

‘Melissa Parris’ retains some of the deciduous nature, large foliage, and large flowers of the seed parent, ‘Silk Road’, however the leaf drop is tardy in contrast, and the leaves have a darker, glossier appearance than the seed parent. The flowers of ‘Silk Road’ are white, while the flowers of new cultivar ‘Melissa Parris’ are smaller and distinctively pink with striations.

‘Melissa Parris’ vividly exhibits aspects of the pink/red floral pigmentation of the pollen parent, ‘Anita Figlar’ (RHS Red Group 53A), but in contrast produces deep pink outer tepals (RHS Red-Purple Group 65A) and alternating pink and white inner tepals. Inner tepals may be further distinguished from either parent by vein-like striations and blends of pink along a white background. ‘Melissa Parris’ flowers are markedly larger than the pollen parent (FIG. 4).

The seed and pollen parents are the best comparisons to the new cultivar ‘Melissa Parris’, as no other clonal introductions have been made from this unique cross.

Upper Side of petiole with sun exposure             can develop a color near RHS 166A. Petioles of shaded leaves             and lower portions of petioles tend to be near RHS 158A. -   Flower:     -   -   1. Natural flowering season.—Mid April-Early June in the             Southeastern US.         -   2. Flowering onset.—Parent tree first bloomed as a 3 year             old seedling. Rooted cuttings have flowered within one year             of production.         -   3. Flower type and habit.—Terminal buds initiate flowers             that most commonly are displayed singly, but occasionally a             subtended companion bud emerges near the completion of             flowering of the primary terminal bud.         -   4. Flower longevity on the plant.—Flowers open the first             time between 6:30 and 8:00 PM remaining open until early             morning when the 6-7 (rarely 9) inner tepals move back into             an overlapping position with the 3 outer tepals remaining             entirely reflexed. Approximately 24 hours after the first             opening, the inner tepals open again more fully than the             previous night and shed their stamens. Flowers retain the             blend of dark pink (RHS Red-Purple Group 65A) and creamy             pink (RHS Red-Purple Group 65B) effectively into the 3^(rd)             day without looking spent and discolored like many magnolias             in the post male phase. Flower is self-cleaning. Stamens             abscise and shed by the 3^(rd) day. Tepals shed before the             conclusion of the 3^(rd) day or early in the 4^(th) day. The             2 days of tepal movements have been observed on cut branches             in vases, making the new cultivar ‘Melissa Parris’ an ideal             cut flower specimen.         -   5. Quantity of flowers.—1 in 2014 (3 years post             germination); 30 in 2015 (4 years post germination);             approximately 100 in 2016 (5 years post germination) on             parent tree.         -   6. Flower size.—Diameter — 16-18 cm, while fully open in             2^(nd) evening, male phase. Height — 16-18 cm, while closed             in 2^(nd) day, post female phase.         -   7. Flower shape.—Ovoid when closed in tight bud. Narrow bowl             shape in profile when fully open the first evening. Upright             tepals form obovoid shape when closed on the second day             while three other tepals remain reflexed. Flower assumes a             wide bowl shape the second evening and 3^(rd) day, when all             parts begin to abscise.         -   8. Peduncle.—Length — 3.5-4.0 cm. straight on terminal buds             of ascending branches, curved upward on terminal buds of             lateral branches. Diameter — Approximately 0.75 cm. Color —             Near RHS Yellow-Green Group 147.         -   9. Tepals.—Color — Outer: RHS Red-Purple Group 65A (FIG. 3);             Inner: White (RHS N155B) with stations and blends of RHS             Red-Purple Group 65A. Arrangement — Alternately whorled,             overlapping. Shape — Spatulate — Obovate, Cupped. Size —             Length 8.0-9.0 cm, Width — 3.8-4.5 cm at widest point.             Margin — Entire. Apex — Obtuse. Base — Short-clawed. Tepal             Quantity — 9-12, Commonly 10. Texture — Glabrous on upper             and lower surfaces.         -   10. Fragrance.—Intense blend of sweet citrusy fragrances. -   Reproductive organs: -   Gynoecium: Approximately 1.25 cm. (at widest point)×2.5 cm long.     -   -   Pistils.—Approximately 40. Stigmatic surface is recoiled             when receptive at initial opening and extends along the             pistil length approximately 0.2 cm. White (RHS 155D) prior             to tepal opening, and Light Orange (RHS 29A) when open. -   Androecium: Approximately 0.6 cm. long×0.6 cm. diameter.     -   -   Stamens.—Exceeding 100.
